I don't have anything really profound to add to what the others have posted, but my heart was touched by your pain and I just want to offer you support. And also to say, please don't turn completely away from what your T can offer you at this point.....you're being realistic in the sense that, yes, the T relationship is not a substitute for real world relationships, yet you do have the right to the comfort and support it can offer you right now when you have the very real need for it - don't deny yourself that when you do need it! It sounds to me as if your T is one who is able to fulfill that need.....
And you are loved...you are worthy of being loved.
